Most Linux systems have a default bash prompt in one color that tells you your user name, the name of the machine you’re working on, and some indication of your current working directory. This is all useful information, but you can do much more with the prompt. All sorts of information can be displayed. You can even change the colors either to make it look interesting, or to make certain information stand out. You might also want to customize your bash prompt if you have difficulties using the terminal because the prompt isn’t visible enough.
